BACKGROUND

1. Technical Field

The present invention relates to an optical image lens assembly. More particularly, the present invention relates to a compact optical image lens assembly applicable to electronic products.

2. Description of Related Art

In recent years, with the popularity of mobile products with camera functionalities, the demand for miniaturizing an optical lens system is increasing. The sensor of a conventional photographing camera is typically a CCD (Charge-Coupled Device) or a CMOS (Complementary Metal-Oxide-Semiconductor) sensor. As advanced semiconductor manufacturing technologies have allowed the pixel size of sensors to be reduced and compact optical lens systems have gradually evolved toward the field of higher megapixels, there is an increasing demand for compact optical lens systems featuring better image quality.

A conventional compact optical lens system employed in a portable electronic product mainly adopts a four-element lens structure, such as U.S. Pat. No. 7,869,142. Due to the popularity of mobile products with high-end specifications, such as smart phones and PDAs (Personal Digital Assistants), the pixel and image-quality requirements of the compact optical lens system have increased rapidly. However, the conventional four-element lens structure cannot satisfy the requirements of the compact optical lens system.

Another conventional compact optical lens system has five-element lens structure, such as U.S. Pat. No. 7,911,711. However, it cannot effectively reduce the total track length of the optical lens system by providing a convex object-side surface on a first lens element which is closest to the object. Moreover, the refractive power of the first lens element cannot be balanced by the excessive difference of the curvature between the object-side surface and the image-side surface thereof, so that the aberration and the spherical aberration of the optical lens system would be generated and decreasing the image quality.

DETAILED DESCRIPTION

An optical image lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element.

The first lens element with positive refractive power has a convex object-side surface and a convex image-side surface, so that the positive refractive power of the first lens element is proper for reducing the total track length of the optical image lens assembly. Moreover, the first lens element has at least one inflection point on the object-side surface thereof, so that the incident angle of the off-axis field into the optical image lens assembly and the aberration can be effectively reduced.

The second lens element with negative refractive power has a concave object-side surface and a convex image-side surface, so that the aberration generated from the first lens element with positive refractive power and the astigmatism of the optical image lens assembly can be corrected.

The third lens element with negative refractive power can reduce the high order aberration of the optical image lens assembly. When the third lens element has a concave object-side surface and a convex image-side surface, the astigmatism of the optical image lens assembly can be corrected.

The fourth lens element with positive refractive power can balance the positive power distribution of the optical image lens assembly so as to reduce the sensitivity of the optical image lens assembly. The fourth lens element has a concave object-side surface and a convex image-side surface, so that the astigmatism of the optical image lens assembly can be corrected.

The fifth lens element with negative refractive power has a concave image-side surface, so that the principal point of the optical image lens assembly can be positioned away from the image plane, and the total track length of the optical image lens assembly can be reduced so as to maintain the compact size of the optical image lens assembly. The fifth lens element has at least one inflection point on at least of the object-side surface and the image-side surface thereof, so that so that the incident angle of the off-axis field on an image sensor can be effectively reduced and the aberration can be further corrected as ell.

When a curvature radius of the object-side surface of the first lens element is R1, and a curvature radius of the image-side surface of the first lens element is R2, the following relationship is satisfied:

−2.0<R2/R1<0.

By such arrangement, the shape of the surfaces of the first lens element is proper. The convex object-side surface and the convex image-side surface of the first lens element can enhance the refractive power thereof, so that the optical image lens assembly can retain the telephoto characteristic for further reducing the total track length of the optical image lens assembly applied to compact electronic products. Furthermore, the refractive power can be evenly distributed on the surfaces of the first lens element, so that the aberration generated from the excessive surface curvature can be reduced, and the spherical aberration of the optical image lens assembly can also be corrected for enhancing the image quality.

R2 and R1 can further satisfy the following relationship:

−1.0≦R2/R1<0.

When a curvature radius of the object-side surface of the second lens element is R3, and a curvature radius of the image-side surface of the second lens element is R4, the following relationship is satisfied:

−1.0<(R3−R4)/(R3+R4)<1.0.

Therefore, the negative refractive power of the second lens element is proper by adjusting the curvature of the surfaces of the second lens element, so that the second lens element can retain the ability for correcting the aberration, and the spherical aberration of the optical image lens assembly can be also corrected.

When a curvature radius of the image-side surface of the third lens element is R6, and an axial distance between the third lens element and the fourth lens element is T34, the following relationship is satisfied:

−8.0<(T34/R6)×100<0.5.

Therefore, the fabricated yield of the optical image lens assembly can increase by adjusting the distance between the third lens element and the fourth lens element and the curvature of the image-side surface of the third lens element.

T34 and R6 can further satisfy the following relationship:

−6.0<(T34/R6)×100<0.

When the curvature radius of the image-side surface of the second lens element is R4, and a curvature radius of the object-side surface of the third lens element is R5, the following relationship is satisfied:

0<R5/R4<0.80.

By such arrangement, when the second lens element has positive refractive power and the third lens element has negative refractive power, the aberration of the optical image lens assembly can be corrected. When the second lens element and the third lens element have negative refractive power, the sensitivity of the optical image lens assembly can be reduced by balancing the distribution of the negative refractive power thereof.

R5 and R4 can further satisfy the following relationship:

0<R5/R4<0.50.

When a focal length of the optical image lens assembly is f, and a focal length of the second lens element is f2, the following relationship is satisfied:

−0.50<f/f2<0.50.

Therefore, the second lens element with proper refractive power can correct the aberration generated from the first lens element with positive refractive power effectively.

f and f2 can further satisfy the following relationship:

−0.50<f/f2<0.

When an Abbe number of the first lens element is V1, an Abbe number of the second lens element is V2, and an Abbe number of the third lens element is V3, the following relationship is satisfied.

0<(V2+V3)/V1<1.0.

Therefore, the chromatic aberration of the optical image lens assembly can be corrected.

When an axial distance between the object-side surface of the first lens element and the image-side surface of the fifth lens element is TD, the following relationship is satisfied:

2.0 mm<TD<4.5 mm.

Therefore, the total track length of the optical image lens assembly can be reduced so as to maintain the compact size thereof.

When an axial distance between the first lens element and the second lens element is T12, an axial distance between the second lens element and the third lens element is T23, the axial distance between the third lens element and the fourth lens element is T34, and an axial distance between the fourth lens element and the fifth lens element is T45, the following relationship is satisfied:

0<(T34+T45)/(T12+T23)<1.9.

Therefore, the fabricated yield of the optical image lens assembly can increase by adjusting the distance between lens elements.

When a half of the maximal field of view of the optical image lens assembly is HFOV, the following relationship is satisfied:

38 degrees<HFOV<60 degrees.

When the optical image lens assembly has excessive field of view, the deformation at the peripheral region of the image would be obvious. When the optical image lens assembly has insufficient field of view, the image capturing range would be restricted. Therefore, the proper field of view can provide the proper image capturing range and increase the image quality.

HFOV can further satisfy the following relationship:

40 degrees<HFOV<50 degrees.

When a curvature radius of the object-side surface of the fifth lens element is R9, and a focal length of the optical image lens assembly is f, the following relationship is satisfied:

0<R9/f<2.0.

Therefore, the Petzval Sum of the optical image lens assembly can be corrected for smoothing the peripheral area of the image.

According to the optical image lens assembly of the present disclosure, the lens elements thereof can be made of glass or plastic material. When the lens elements are made of glass material, the distribution of the refractive power of the optical image lens assembly may be more flexible to design. When the lens elements are made of plastic material, the cost of manufacture can be effectively reduced. Furthermore, the surface of each lens element can be aspheric, so that it is easier to make the surface into non-spherical shapes. As a result, more controllable variables are obtained, and the aberration is reduced, as well as the number of required lens elements can be reduced while constructing an optical system. Therefore, the total track length of the optical image lens assembly can also be reduced.

According to the optical image lens assembly of the present disclosure, when the lens element has a convex surface, it indicates that the paraxial region of the surface is convex, and when the lens element has a concave surface, it indicates that the paraxial region of the surface is concave.

According to the optical image lens assembly of the present disclosure, the optical image lens assembly can include at least one stop, such as an aperture stop, glare stop, field stop, etc. Said glare stop or said field stop is allocated for reducing stray light while retaining high image quality. Furthermore, when a stop is an aperture stop, the position of the aperture stop within an optical system can be arbitrarily placed in front of the entire lens assembly, within the lens assembly, or in front of the image plane in accordance with the preference of the optical designer, in order to achieve the desirable optical features or higher image quality produced from the optical system.
